On the other side, Romney's weaknesses are ... what they consistently are. He underperfoms among independents and women and his business background isn't an unalloyed asset:

In the current poll, crucial independent voters prefer Obama to Romney, 46 percent to 41 percent. While Romney leads comfortably among men in Florida, Obama has a 14-point lead among women. ...

Forty-seven percent said Romney's business background gives him the skills to better manage the government and improve the economy. But 38 percent agreed with the statement that "he is more concerned with making money and his practices in many instances have unnecessarily cost people their jobs in order to earn profits."

Of the three biggest toss-up states — Florida, Ohio and Virginia — this is the one that currently looks best for Romney, but the race there is obviously far from over.
